The actual fixed-atlas correction bounds imply a smooth manifold limit and convergence of the manifold differentials.

    Source documentation

    Where its outer cutoff is one, the coordinate representative agrees with the original map, for every map simultaneously.

  3. theorem OAI.ClosedSurfaceR4.FiniteOrderSmoothing.SmoothingAtlas.correction_limit line 44

    Source documentation

    The global atlas norm can be used directly; the summable bound only has to hold eventually for each fixed derivative order.
